Add event tracing mechanism for following routines: - rtrs_clt_reconnect_work() - rtrs_clt_close_conns() - rtrs_rdma_error_recovery() How to use: 1. Load the rtrs_client module 2. cd /sys/kernel/debug/tracing 3. If all the events need to be enabled: echo 1 > events/rtrs_clt/enable 4. OR only speific routine/event needs to be enabled e.g. echo 1 > events/rtrs_clt/rtrs_clt_close_conns/enable 5. cat trace 6. Run some workload which can trigger rtrs_clt_close_conns() Link: https://lore.kernel.org/r/20220818105240.110234-2-haris.iqbal@ionos.com Signed-off-by: Santosh Pradhan <santosh.pradhan@ionos.com> Signed-off-by: Jack Wang <jinpu.wang@ionos.com> Signed-off-by: Md Haris Iqbal <haris.iqbal@ionos.com> Signed-off-by: Leon Romanovsky <leon@kernel.org>
